To do...
Configure the VTY
redrawing hotkey
Configure the terminal
reset hotkey
Configure the maximum
size of data to be sent to a
terminal at one time
Configure the terminal
send buffer threshold
Configure the connectivity
test hotkey
Configure TCP parameters tcp { keepalive time count
Configure a description for
a VTY
Configure the character
string for triggering VTY
screen saving
Configure the VTY
switching hotkey
Update the configuration
If both the global source IP address and the source IP address for a VTY are
■
configured, the one for the VTY is used.
The TCP parameters must be configured before TCP connections are
■
established. If you configure the parameters after a TCP connection is
established, the TCP connection must be reestablished for the parameters to
take effect. Pressing the reset hotkey on the terminal can reestablish the TCP
connection.
Receive buffer size must be configured before the terminal template is applied.
■
If you configure the receive buffer size after a terminal template is applied, you
need to remove the application of the terminal template and apply the terminal
template again for the receive buffer size to take effect.
The ASCII value of the hotkey must be different from the ASCII value of any
■
other hotkey configured on the device. Otherwise, hotkey conflicts will occur.
For example, the hotkey value cannot be set to 17 or 19 because these two
values are used for the hotkeys of flow control. In addition, using the hotkey
may not get a response rapidly when the terminal displays too much data.
Configuring the TTY Receiver
The receiver of TTY terminal access is an FEP. The main program of terminal access
at an FEP is the program ttyd (ttyd executable), which implements the data
